[media] saa7134: Properly report when a board doesn't have eeprom

Browse Source 
When a device is not detected, the driver prints a warning message.
That's ok, except for the fact that, even on newer devices that have
eeprom but aren't yet supported, it prints a message saying that the
device doesn't have eeprom.

Fix it by having a separate message for devices with eeprom, but not
yet known by the driver.
